Fix crash retrieving a PyObject type property via QVariant<PyObjectWrapper>

The old code registered a Shiboken converter for PyObjectWrapper by
pointer conversion. This resulted in the Python to C++ converter
falling back to plain pointer passthrough since it only works for
SbkObjects.

The C++ to Python conversion worked by coincidence for either raw
PyObject * pointers used in meta call handling or pointers obtained
from calling QVariant<PyObjectWrapper>.data(), but without handling
reference counts.

To fix this, remove the Python to C++ conversion entirely and do this
manually via QVariant. Change the C++ to Python to be by value and use
PyObjectWrapper.
